Subject: [dpdk-dev] [PATCH 2/2] net/bnxt: set Rx checksum flags in vector mode receive
Date: Mon, 29 Jul 2019 17:28:25 -0400 [thread overview]
Message-ID: <20190729212825.5077-1-lance.richardson@broadcom.com> (raw)
From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
Fixed to return the checksum status of rx packets by setting
"ol_flags" correctly in vector mode receive.
These changes have been there for non vector mode receive.
In vector mode receive also indicate inner and outer checksum
errors individually in "ol_flag" to indicate L3 and L4 error.
Fixes: bc4a000f2f53 ("net/bnxt: implement SSE vector mode")
